Abstract

Dischidia is an epiphytic plant, it is used as herbal medicine and has economic value. In addition, Dischidia also has an ecological function. Moreover, some species of Dischidia are endemic in a particular region. Various forest types occur in Bangka Island serves as natural habitat for this epiphytic plant. This research aimed to record the diversity and abundance of Dischidia and analyze those environmental factors which affect its abundance. The research was conducted in August – September 2016 at Bangka Island. Three plots of 20 × 20 m² were placed with a minimum interval of 50 m in the habitat where Dischidia are found. The species diversity and abundance of Dischidia as well as abiotic factors such as temperature, humidity, light intensity, wind speed, and altitude were recorded in these plots. The vegetation structure was analyzed based on index of diversity, index of dominancy and index of evenness. Data on the environmental condition and abundance of Dischidia were then analyzed using Canonical Correspondence Analysis (CCA) method with Canoco 4.5 software. Five species of Dischidia were found in Bangka Island that are Dischidia bengalensis, Dischidia imbricate, Dischidia nummularia, Dischidia rafflesiana, and Dischidia hirsute. Dischidia is found in 14 species of host plants. D. imbricate (23 individual plants) occurred in the heath forest at Pejem showed the highest abundance. Epiphytic fern plants, the Asplenium nidus (27 individual plants), was the dominant epiphytes found in the host tree of Dischidia The CCA showed that light intensity, temperature and humidity influenced the abundance of Dischidia.

Abstract

Anatomical structures may vary among the species of Nepenthes. Therefore, the anatomical characters apparently could be used for supporting the morphological characters in identifying species. This study aimed to seek a valuable anatomical character for identifying and defining five species of Nepenthes occur in Bangka Belitung Islands. Samples of leaves, pitchers and its lids of Nepenthes gracilis, Nepenthes mirabilis, Nepenthes ampullaria, Nepenthes rafflesiana, and Nepenthes reinwardtiana were collected and prepared for paradermal and transverse section of microscope slides. The results showed that the anatomical characters of the leaves, pitchers and lids from these five species of Nepenthes could be used for differentiating five species Nepenthes observed. The absence of nectary gland at the abaxial of pitcher lids of N. gracilis and N. ampullaria separate them from others species. The leaf epidermis of these two species have different cell wall. The length of lunate cells at the inner surface of upper half pitchers are comparable for identifying the pitchers of N. mirabilis from those of N. reinwardtiana.  The presence of crystal at the parenchymal tissue of pitcher differentiate N. rafflesiana from the four others.  In this research, the identification key for Nepenthes from Bangka Belitung Islands based on the anatomical character was presented.
